Probing the atmosphere of HD189733b with the Na I and K I lines
E. Keles, D. Kitzmann, M. Mallonn +12
High spectral resolution transmission spectroscopy is a powerful tool to characterize exoplanet atmospheres. Especially for hot Jupiters, this technique is highly relevant, due to…
Role of the impact parameter in exoplanet transmission spectroscopy
X. Alexoudi, M. Mallonn, E. Keles +3
Transmission spectroscopy is a promising tool for the atmospheric characterization of transiting exoplanets. Because the planetary signal is faint, discrepancies have been reported…
The effect of varying atmospheric pressure upon habitability and biosignatures of Earth-like planets
Engin Keles, John Lee Grenfell, Mareike Godolt +2
Understanding the possible climatic conditions on rocky extrasolar planets, and thereby their potential habitability, is one of the major subjects of exoplanet research. Determinin…
High-resolution spectroscopy and spectropolarimetry of the total lunar eclipse January 2019
K. G. Strassmeier, I. Ilyin, E. Keles +5
Observations of the Earthshine off the Moon allow for the unique opportunity to measure the large-scale Earth atmosphere. Another opportunity is realized during a total lunar eclip…
The potassium absorption on HD189733b and HD209458b
Engin Keles, Matthias Mallonn, Carolina von Essen +9
In this work, we investigate the potassium excess absorption around 7699A of the exoplanets HD189733b and HD209458b. For this purpose, we used high spectral resolution transit obse…
Ephemeris refinement of 21 Hot Jupiter exoplanets with high timing uncertainties
M. Mallonn, C. von Essen, E. Herrero +32
Transit events of extrasolar planets offer a wealth of information for planetary characterization. However, for many known targets, the uncertainty of their predicted transit windo…
